Link aggregation issues Solaris 10

UNIX Solaris
1

I have setup link aggregation with 3 interfaces on my solaris 10 system.

All looks good but my problem is that the traffic is only going out bge0 and not the other 2 links.

bash-4.3# dladm show-aggr -s
key:33          ipackets   rbytes       opackets   obytes       %ipkts  %opkts
        Total   2423536    169265389    693        44352
        bge0    1844204    122846897    693        44352          76.1   100.0
        bge1    289672     23209454     0          0              12.0     0.0
        bge2    289660     23209038     0          0              12.0     0.0

I tried configuring the aggregation with different levels.
L2, L3 and the default L4 but always the same.

Primeaup,

~700 packets is not a lot of traffic.

It's been a week, are you still seeing the imbalance?

Good morning thanks to all for getting back to me.

I was able to get a bit more balance between the links by applying the LAC option.

Those this look better I edited it and used the code tag function.

Like this with the code tag.

If your LAN switch has active LACP enabled, then you better set LACP mode to passive and LACP timer to long:

dladm show-aggr -L
dladm modify-aggr -l passive -T long 33
dladm show-aggr -L
